Nickel-containing wastewater treatment device for printed circuit board

The utility model relates to the field of wastewater treatment, in particular to a nickel-containing wastewater treatment device for a printed circuit board, which adopts the technical scheme that the nickel-containing wastewater treatment device comprises a wastewater storage tank, a mixing tank is arranged on one side of the wastewater storage tank, a settling tank is mounted at the lower end of the mixing tank, and a winding component is mounted above the settling tank; the wastewater treatment device has the beneficial effects that before wastewater is settled, the collecting plate is lowered to the bottom of the inner cavity of the settling tank by utilizing the winding assembly, after the wastewater and a reaction reagent are mixed, stirred and guided into the settling tank, generated sediments sink into the inner side of the groove, and after the wastewater is settled, the sediments are separated from the inner cavity of the settling tank. The collecting plate is lifted upwards through the winding asse
